Step 1: Connect PC1 to S1 using a console cable.
a. Click the Connections icon (the one that looks like a lightning bolt) in the lower left corner of the Packet Tracer window.
c. Click PC1. A window displays an option for an RS-232 connection.
e. Select the Console port to complete the connection.
Step 2: Establish a terminal session with S1.
a. Click PC1 and then select the Desktop tab.
b. Click the Terminal application icon. Verify that the Port Configuration default settings are correct.
c. Click OK.
d. The screen that appears may have several messages displayed. Somewhere on the screen there should be a Press RETURN to get started! message. Press ENTER.
What is the prompt displayed on the screen? S1>
Part 2: Explore EXEC Modes
In Part 2 of this activity, you will switch to privileged EXEC mode and issue additional commands.
Step 1: Enter privileged EXEC mode.
a. At the prompt, type the question mark (?).
S1> ?
S1> t?
S1> te?
S1>?
b. Type en and press the Tab key.
S1> en<Tab>
Step 2: Enter Global Configuration mode.
a. When in privileged EXEC mode, one of the commands starting with the letter ‘C’ isconfigure. Type either the full command or enough of the command to make it unique. Press the <Tab> key to issue the command and press ENTER.
S1# ?
S1# configure
b. This is called global configuration mode. This mode will be explored further in upcoming activities and labs. For now, return to privileged EXEC mode by typing end,exit, or Ctrl-Z.
S1(config)# exit
S1#
Part 3: Set the Clock
Step 1: Use the clock command.
a. Use the clock command to further explore Help and command syntax. Type showclock at the privileged EXEC prompt.
S1# show clock
b. Use the context-sensitive Help and the clock command to set the time on the switch to the current time. Enter the command clock and press ENTER.
S1# clock<ENTER>
c. The “% Incomplete command” message is returned by the IOS. This indicates that theclock command needs more parameters. Any time more information is needed, help can be provided by typing a space after the command and the question mark (?).
S1# clock ?
d. Set the clock using the clock set command. Proceed through the command one step at a time.
S1# clock set ?
e. Based on the information requested by issuing the clock set ? by using the 24-hour format of 06:08:00. Check to see if more parameters are needed.
S1# clock set 06:08:00 ?
f. Attempt to set the date to 01/31/2035 using the format requested. It may be necessary to request additional help using the context-sensitive Help to complete the process. When finished, issue the show clock command to display the clock setting. The resulting command output should display as:
S1# show clock
*6:18:4.9 UTC Sat Jun 29 2019
g. If you were not successful, try the following command to obtain the output above:
S1# clock set 06:08:00 29 Jun 2019
Step 2: Explore additional command messages.
a. The IOS provides various outputs for incorrect or incomplete commands. Continue to use the clock command to explore additional messages that may be encountered as you learn to use the IOS.
b. Issue the following command and record the messages:
S1# cl
What information was returned? % Ambiguous command: “cl”
S1# clock
What information was returned? % Incomplete command.
S1# clock set 25:00:00
What information was returned?
S1#clock set 25:00:00
% Invalid input detected at ‘^’ marker.
S1# clock set 15:00:00 32

5. To secure access to the console line, access config-line mode and set the console password to letmein.
S1# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
S1(config)# line console 0
S1(config-line)# password letmein
S1(config-line)# login
